Dimensions are 55 mm wide, 140 mm high, 149 mm deep. The 55 mm width is three 18 mm module spaces, so it occupies three slots on a DIN rail. Main circuit terminals accept screw-type connections, with M6 bolts for the main contacts. Breaking capacity varies by voltage: 25 kA at 240 V and 400 V, 6 kA at 500 V, 3 kA at 690 V. For AC circuits, the figures are higher: 50 kA at 240 V and 400 V AC, 12 kA at 500 V AC, 5 kA at 690 V AC. These numbers tell you where this breaker can sit in a distribution hierarchy — at 400 V it has headroom for most sub-distribution boards, but at 690 V the 3 kA rating means it needs upstream current-limiting protection if the prospective fault current exceeds that. ## Environmental and storage specs The -50 °C lower limit is unusual for a circuit breaker; most stop at -25 °C, so this one handles cold environments like refrigerated warehouses or outdoor enclosures in northern climates.","metaTitle":"Siemens 3RV2031-4SA15-0BA0 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV2031-4SA15-0BA0 motor protection circuit breaker, CLASS 10 trip, 3 kW at 230 V, 25 kA breaking at 400 V.

However, verify the terminal arrangement and wire sizes — the 3RV2031 accepts 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded conductors, which may differ from the 3RV2021's terminal specs.
